I have recently been made aware of a new beard trend called the "monkeytail". I could explain, but allow me to just illustrate it instead:
The hair dye is a non-essential part of the look, but you get the idea. This trend even has its own website here. I'm not the biggest fan in the world of weird beards, but at the same time if somebody wants to go for something unique it's certainly not my place to tell them they shouldn't. In any case, I'm still not sure if I like this look, but it's certainly interesting and I can see the odd sort of appeal it would have.
